Definitions

  • the claimed invention relates to the improvement of the nutritive value of soybean meal and other vegetable seed proteinaceous meals for feeding to ruminant animals. More particularly, the invention is concerned with improved meal compositions in which the protein content of the meal is protected from degradation within the rumen of the consuming animal, and the method for producing such meal compositions.
  • soybean meal With reference to feeding value lost by rumen destruction, soybean meal has a relatively low protein efficiency value. See Klopfenstein, Feedstuffs, Jul., 1981, 23-24. Since soybean meal is one of the major protein-containing feed materials used with ruminants, it is particularly desirable to provide a commercially practical means for protecting soybean meal against rumen destruction. For large scale commercial use such a method must be simple, efficient, and of relatively low cost. Such a method should thus be capable of being integrated into existing commercial facilities for processing soybeans and the like into feed materials.
  • U.S. Pat. No. 3,619,200 proposes the application to a vegetable meal or other proteinaceous ruminant feed material of a rumen resistant coating.
  • the purpose of the coating is to protect the proteinaceous feed from microbial attack in the rumen, followed by the decomposition of the coating in order to allow digestion of the feed within the abomasum and small intestine.
  • Tagari et al. compared solvent extracted soybean meals of different heat exposures. These included room temperature solvent removal, solvent removal at 80 ° C. for 10 minutes, and commercial toasted meal steamed at 120° C. for 15 minutes. The meals were fed to rams and rumen liquor samples were tested. Artificial rumen comparisons for ammonia liberation were also made. It was concluded that the main factor determining the different efficiencies of process to non-process soybean meals is their different solubility in rumen liquor. It was also observed that changes in solubility caused by different heat treatments of soybean meal are relatively large in comparison with other meals.
  • Anderson discloses a procedure for preparing a growth factor for feeding domestic animals and poultry.
  • a zinc salt in aqueous solution such as zinc chloride or zinc sulfate, is reacted with free amino acids in a proteinaceous feed material.
  • the reaction is carried out in an aqueous solution at a temperature of 60°-70° C. (140°-158° F.), and a pH of 3.5, which pH is said to be achieved automatically with ZnCl 2 , an adjustment of pH with HCl being used with other zinc salts.
  • the reaction mixture is dried to a moisture content of 2-8%, and mixed with the feed ration. There is no reference to the feeding of ruminants, or to rumen protection of protein.
  • Emery et al. describes a process in which mineral compounds including zinc and other polyvalent metal oxides, hydroxides, and salts are reacted with proteinaceous feed materials in the presence of water and a protein splitting acid such as H 3 PO 4 , HCl, or H 2 SO 4 .
  • the reacted mixture is dried by heating in air.
  • Soybean meal is indicated as the preferred feed material and zinc is among the metals referred to for use in the form of oxides, hydroxides, or carbonates.
  • Other salts, such as cobalt are indicated as being used in the form of chlorides or sulfates.
  • the examples illustrate the reaction of large amounts of the metal compounds with soybean meal (Ex. I, 35% and Ex. III 17%, based on the meal). There is no reference in this patent to either rumen protection or nutritional value.
  • Ashmead proposes the use of metal proteinates for supplying mineral deficiencies in humans and animals.
  • the proteinates are prepared by reacting bivalent metal salts at an alkaline pH with free amino acids of enzyme-hydrolyzed proteins.
  • the rumen by-pass potential normally obtained through the inclusion of 0.015-0.02 units of zinc per unit of protein in a meal using dry mixing can be obtained through the use of only about 0.003-0.008 parts of zinc per part protein in the meal, a 60-70% reduction in the amount of zinc, if the zinc and defatted soy flakes are contacted under moist heat conditions. Under such conditions, the total moisture content of the zinc/meal mixture is in the range of 15-30%, with about 20% total moisture being preferred.
  • the heating of the zinc/meal mixture can be carried out in a commercial toaster, at a temperature of 180°-230° F., for 10-30 minutes.
  • the heating can also take place in a combined roaster/conditioner at a temperature of 280°-300° F. Surprisingly, it has also been found that a similar rumen-bypass potential can be obtained if the heating is carried out for much shorter periods of time in a commercial extruder.
  • Enzyme indigestibility determined by measuring, in vitro, the rate and extent of protein degradation by protease, is a useful tool for evaluating the rumen by-pass potential of various feeds. Suitable test procedures are described in Poos et al., "A Comparison of Laboratory Techniques to Predict Ruminal Degradation of Protein Supplements", J. Anim. Sci. Abstra. 679, p. 379 (1980); and Rock et al., “Estimation of Protein Degradation with Enzymes", J. Anim. Sci. Abstra. 121, p. 118 (1981).

  • Higher levels of zinc can be used but are not needed. Indeed, in keeping with the objectives of this invention, excesses of zinc should be avoided. Lower levels may also be used, which will generally result in a decrease in the rumen-bypass potential of the treated protein.

  • One half of the meal remained untreated and served as the control.
  • the remaining half was treated as follows.
  • the 48% protein soybean meal was mixed with 1875 ppm of zinc ion from zinc sulfate and then exposed to 15 pounds of steam for 20 minutes in a closed vessel. Condensing steam raised the moisture of the meal to about 20%. After heat treatment, the meal was dried to 12% moisture using pellet cooler fitted with fine mesh screen, bagged and stored until used.
  • In vitro degradability analysis using the ficin assay showed the untreated and treated meals to have an available undegraded nitrogen (% AUN) of 19.8% and 60.9% respectively.
  • the ration containing treated soybean meal demonstrated improved daily weight gain (3.11 pounds versus 3.00 pounds for untreated). Pounds of dry matter consumption per pound of gain were reduced in steers receiving the treated soybean meal (5.32 for treated and 5.65 for untreated). Since weight gains were improved with a reduction in dry matter intake, feeding efficiency favored those steers consuming the treated soybean meal. These data indicate that a successful bypass protein can be produced when 48% protein toasted soybean meal is treated with low levels of zinc and moist heat.

The toasted meal was blended with 130 pounds of water per ton and 80 pounds per ton feed grade fat. This blend was processed through an INSTA-PROTM 2000 extruder. Temperature at the exit was 275° F. Production rate was 1800 pounds per hour. The ficin value of the treated meal was 50.7%, plus or minus 3.6%.
  • a single lot of 48% protein toasted soybean meal was obtained. One half of the meal was set aside for use as the control. The other half was blended with 1875 ppm of zinc ion from zinc sulfate.
  • the zinc ion containing toasted soybean meal was processed through a WengerTM X-155 extruder under the following conditions: Barrel--6 heads; die, peripheral; 156 round holes, each 3/16 inch diameter (3 rows of holes), two rows of 54 and one row of 48; knife, 4 blades.
  • the toasted soybean meal containing zinc ions was fed at a rate of 1200-1300 pounds per hour. Water feed rate was 300 pounds per hour at 150° F., 190° F. at the downspout.
  • the % AUN of the treated meal after extrusion was 71.5.
  • Eighty cross-bred steers averaging 704.1 pounds were randomly allotted into eight groups of 10 steers each on the basis of breed and weight.
  • a ration consisting of a full feed of corn silage, 5 pounds of shelled corn per head per day and 1.5 pounds of supplement BGP-830 were fed.
  • a Rumensin-Tylan carrier formed the rations which were either full-fed or restricted to 1.75 to 2.04% of body weight.
  • the results of the experiments showed that daily gains were significantly improved (1.94 pounds versus 2.20 pounds) in those steers receiving the low level zinc treated soybean meal (P ⁇ 0.01).
